Vertex Colour/Materials

I’m trying to convert a Vray model to Corona - the Vray model was done in GrowFX utilising it’s Vertex Colour features.

The original Vray material’s diffuse map was a composite with Vertex Colour as the bottom layer and a greyscale leaf texture in the second layer set to Overlay 100%.

If I try to recreate just the diffuse map in Corona the material previews are wildly different.

I’ve attached the two - Vray is how it should look.

Anyone know what’s happening?

Did you use CoronaMix node? If so, did you tried to check/uncheck perform mixing in sRGB mode?

I initially just did it a composite map as per the original - i then tried the Corona mix with that option both checked and unchecked - all 3 gave me the same result

Could you check if vertex colours are still working? Maybe it get lost somehow?

I’ll check this later and let you know
